Advancing a conceptual model of evidence-based practice implementation in public service sectors.

"Funding Just as usual care services must be funded, sustaining EBP after initial implementation requires a commitment to ongoing funding. Funding can be dedicated to the support of the particular practice or can be allocated more generally for supporting the services—and associated organizations and staff—in the implementation setting. However, some additional costs are generally associated with EBP that go beyond usual services such as costs associated with monitoring the fidelity with which an intervention is delivered and then providing relevant feedback, coaching, or support to service providers. Additional costs are also associated with training new staff in the EBP and, in many cases, supporting staff until they are certified in the practice. This can be a particularly critical issue in public sector service organizations where turnover rates can range from 20% to 50% annually. A concern for many service systems is supporting EBPs—that are generally more costly to deliver than usual care services—while reaching clients in need. This translates into a challenge for service organizations that have to balance providing high quality care while meeting productivity requirements."
